  • 1.0M (QE2445)
  • 3.0M (QE2448)

Signature Audio 40 is a never before seen design concept from QED labs. The cordage is designed primarily for low capacitance as this has been identified by QED as one factor which leads to a hi-fidelity experience making for a tight sound and retaining the rhythm of the original piece.

Add Complimentary Conductor TechnologyTM for high frequency detail and our Analoc TechnologyTM to maximise signal integrity and the result is what we feel to be the most innovate interconnect ever seen by QED. Please see our ''cables matter'' section below for more in depth information on this ground breaking design.

Complimentary Conductor TechnologyTM
This innovation utilises two conductors of different diameters to carry the same audio signal. This has the effect of providing an alternative path for high frequency audio components which might otherwise become time smeared in a single audio pathway.

TEFLON DIELECTRIC
The low constant dielectric material of Teflon has been used to cut down on the amount of audio signal energy lost due to cable capacitance.

CRYOGENIC TREATMENT
It is understood that Cryogenic treatment results in the elimination of dislocations and fractures in the materials micro-structure. Trumpets and other brass instruments have been found to produce a better tone after Deep Cryogenic Treatment and also extends their working life. Our extensive listening tests have shown that the cryogenically treated cable is preferred over the same cable without the treatment.

ANALOCTM Locking RCA Plugs
The new QED Analoc plug is a low eddy current design featuring small high purity copper conductors in place of the usual large volume brass body found in ordinary high quality plugs. This cuts down or eliminates the tendency for the changing magnetic field in the conductor to induce eddy currents which can affect the micro timing of the audio signal. Rhodium plating has the advantage for use as a plating material due to its superior hardness.
